stay longer at 1000 Trails
Most of the 1000 Trails parks allow you to stay longer for a small fee. They are all different, but the park at Medina Lake Texas charges $275 plus 75 electric for an additional 4 weeks. As soon as we are able to go fulll time, we plan on typically staying 6 weeks in each 1000 Trails location. When you work the numbers, it is a good deal.
If you buy off ebay, be careful not to spend too much. You can get the full National membership from the park for about $4000.
